Whether you create a podcast about your marketing expertise or your latest big product, there are apparently plenty of listeners out there. Apple announced that it's iTunes store had reached 1 billion podcast subscriptions recently and even created a special little page in the iTunes store commemorating the event\u00a0(sign in to view it). Listen to the popular podcasts that helped us reach 1 billion subscriptions. @NPR @WNYC @ThatKevinSMith @nerdist http://t.co/DlJ0gUjWO0 \u2014 iTunes Podcasting (@iTunesPodcasts) July 22, 2013 Those subscriptions are to a total of 250,000 different podcasts or shows and are recorded in more than 100 languages, PC World Reports. More than 8 million episodes combined have been published to the iTunes store to date. Podcasts are free to download so neither the creator of the show nor Apple makes any money from the subscriptions. However, businesses long ago discovered the powerful role podcasts could play in establishing expertise and building a brand. A New Podcasts App for the Mobile Age Podcasts may be even more appealing with the increased popularity of mobile technology. For example, Apple recently revamped the podcast app for iOS allowing iPhone users a better experience when browsing, dowloading and subscribing to postcasts. The Next Web reports the new app has iCloud-synced stations that update automatically when new podcasts are published. This will make it easier for iPhone users to follow your show and know when most recent updates become available. The new app lets users create playlists of their favorite podcasts and sync them across all their mobile devices. This means fans or subscribers can now access your podcasts and your brand from where ever they are.
